Filter by:This study is an open-label study aiming at evaluating the long-term safety and the efficacy profile of ABX464 given once a day (QD) at 25 mg in subjects who have been previously enrolled in the ABX464-102 or ABX464-104 studies (OLE and maintenance studies) and who are willing to continue their treatment. All subjects will receive ABX464 given at 25 mg QD. The enrolment in this long-term study will be based on the endoscopic improvement, the willingness of the subject to carry on his/her participation and also based on investigator's judgement. Subjects will be treated with ABX464 for a maximum period of 54 months. Subjects will be followed up quarterly. After the treatment period, subjects will be followed for 4 additional weeks for safety purposes.
This is a study to understand if taking VTX002 daily as a tablet orally is safe and effective in participants diagnosed with moderate to severe ulcerative colitis (UC). Approximately 189 participants will take VTX002 Dose A, VTX002 Dose B, or matching placebo, once daily. The study consists of a 28-day Screening Period (to see if a participant qualifies for the study), a 13-week double-blind period (a participant receives either active Dose A, Dose B or Placebo), a Long-Term Extension (LTE) Treatment Period of up to 39 weeks, an Open-Label Extension (OLE) Treatment Period of up to 143 weeks, and a 2-week Follow-Up Period. The maximal duration of treatment including the Induction Period, LTE and OLE will be 36 months.
The objective of this study is to assess the efficacy of hydroxychloroquine (HCQ) when combined with Mesalamine in reducing clinical and histologic disease activity in patients who have active mild to severe Ulcerative Colitis (UC) and also to assess the immunological effects of hydroxychloroquine in this population. These outcomes will be evaluated both clinically and experimentally. In vitro, flow cytometry will be employed to measure the expression of CTLA-4 on activated CD4+CD25+CD127- Tregs from patients prior to treatment with HCQ, and then at the end of a 4 month follow up period. Suppression assays will be used to determine the functional capacity of the patient derived Tregs. Clinically, patients will be monitored for remission as defined by reduction in patient reported stool frequency and rectal bleeding (mayo sub-score 0 or 1) and endoscopically, by improvement in mucosal appearance (mayo sub-score 0 or 1), all objective measures in the mayo score.
The purpose of this study is to assess the safety and efficacy of PRA023 in participants with moderately to severely active Ulcerative Colitis. The purpose of Cohort 2 of the study is to assess the safety and efficacy of PRA023 in participants with moderately to severely active ulcerative colitis who are companion diagnostic positive. After the completion of the 12-week induction, all participants have the option to continue in the open-label extension for another 38 weeks.
Vedolizumab is a medicine that helps to reduce sensitivity and pain in the digestive system for participants with UC or CD. In this study, adults with UC or CD will be treated with vedolizumab according to their clinic's standard practice. Participants will receive vedolizumab as either an infusion or an injection just under the skin (subcutaneous). The main aim of the study is to observe real-world treatment patterns in participants treated with vedolizumab. The study sponsor will not be involved in how participants are treated but will provide instructions on how the clinics will record what happens during the study.
The TRIUMPH study was designed to build on the existing literature by studying the efficacy of tofacitinib in hospitalized patients with acute severe ulcerative colitis. This trial will provide evidence for a possible new indication for the use of tofacitinib.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and immunogenicity of MK-6194 in participants with active UC.
The study will assess the efficacy and safety of oral MT-1303 compared to placebo at 12 weeks as the induction treatment in subjects with active mild to moderate ulcerative colitis (UC), as well as maintenance treatment with open-label MT-1303 for up to 36 weeks.
The study aims to describe alterations in the contact activation system during active and inactive ulcerative colitis. Contact activation system measures are compared in a cross sectional (healthy controls vs. active disease) and longitudinal (active diasese vs. inactive disease) fashion.
The purpose of this study is to determine whether oral etrasimod is a safe and effective treatment for moderately active ulcerative colitis in adult participants.
